Question

why do we need to berathe out carbon dioxide?​

Answer 1

Explanation:

$\huge\boxed{\tt\purple{❥︎AnSweR༄}}$

• The carbon dioxide produced is a waste product and needs to be removed. ... This is important because if we couldn't remove carbon dioxide from our blood, it would take up all the carrying capacity of our blood and we wouldn't be able to get oxygen to the rest of our body.

Answer 2

Oxygen is the most abundant element in the atmosphere, the air we breathe is oxygen. Being the air that all organisms require the most. Plants, in particular animals, produce oxygen as they absorb carbon dioxide for all of their functions to take place.

Explanation:

• Carbon-dioxide-the air we mammals exhale is entirely made up of carbon-dioxide, which gets mixed up in the environment before being taken up by plants for photosynthesis and other chemical reactions.
• The human body does not require much carbon dioxide because blood transports mostly oxygen and seventy percent of carbon dioxide in the form of bicarbonate.
• Respiration is the process in which gases are exchanged within the body. It guarantees that the body's tissues, cells, and main organs get enough oxygen, and that carbon dioxide, which is a waste product, is adequately removed.
• Diffusion of oxygen and carbon dioxide across cell membranes is how oxygen and carbon dioxide are exchanged.
